What is Radius End Mills?
Radius End Mills are specialized metal cutting tools featuring a rounded corner (R-radius) design. Compared to flat-end mills, they significantly reduce stress concentration and edge chipping risks while enhancing surface finish and tool longevity. Specifically engineered for demanding materials like steel, aluminum, and titanium alloys, these tools excel in precision contouring and 3D machining.
Key Features of Radius End Mills
1. High-Strength Carbide Construction
Ultra-fine grain tungsten carbide delivers 3-5× longer lifespan than HSS, making it ideal for heavy-duty operations.
2. Optimized Geometry & Diseño
- Variable Helix Angle: Dynamically adjusts flute angles to minimize vibration (achieves Ra0.4μm finish)
- Multi-Flute Options: 2/4-flute designs balance chip evacuation and rigidity across roughing to finishing
3. Advanced Coating Technology
Choose between TiAlN/AlCrN coatings to extend tool life in hard materials (p ej., hardened steel, stainless steel).
4. Flexible Radius Selection
R0.5mm-R3mm options precisely match your machining needs, reducing stress concentration.
5. Material Versatility
Performs exceptionally on aluminum, stainless steel, titanium, and even composites – especially effective for deep slots and thin walls.
